Title: Smoke prevention on incinerator exhausts - using final water cooling to drop water content of gas stream
Inventor: IHARA SATOSHI
IPC: B01D53/00
Filed: 1974-09-03
Abstract: Exhaust gases from a waste incinerator are treated as follows to prevent the emission of white smoke (a) the gas is cooled, (b) wet scrubbed, (c) cooled with water to a low temp. to dehumidify it and reduce the saturation of the gas (d) released to atmosphere. The final cooling should reduce the gas temp. to within 25 degrees C of the ambient temp.

Title: Dynamo and battery bicycle lights - has electronic controls and switchgear to selectively connect battery into light circuit
IPC: B62J6/00
Filed: 1974-09-11
Abstract: Bicycle lighting arrangements suffer from the shortcoming of not giving uniform lighting at all times, as the rate of current from the dynamo is dependent on the speed at which the bicycle is travelling. During periods of standstill e.g. at traffic lights, there is no light at all. The present arrangement consists of a usual dynamo (1) driven by one of the wheels, supplying power via a one way switch (2) and an electronic gear (3) to a battery (4) and at the same time mainly to the lights (6 and 7) via connection (8). Lights (6 and 7) are connected also to the battery via switch (5), providing power to the lights either as a make-up current during slow motion or full current during standstill.

Title: Logarithmic periodic aerial for receiving two frequencies - is fitted with H.F. dipoles contained in insulated housing
IPC: H01Q21/30
Filed: 1974-03-05
Abstract: The aerial is intended for receiving television signals in the VHF and UHF bands.
